Enhance your Mini's performance with the ALTA Supercharger Pulley, crafted from lightweight 6061T6 aluminum. This pulley reduces the rotational inertia of the supercharger, significantly enhancing engine responsiveness. Featuring cross-drilled holes over each groove, it improves belt grip and minimizes belt slippage as the belt stretches. Additionally, oversized belt retainers prevent belt jumping.

ALTA offers two reduction sizes: 15% and 17%, each providing distinct benefits.

• 15% Reduction: The standard choice in the market, delivering smooth power increases of approximately 20WHP for safe performance enhancements.
• 17% Reduction: Ideal for those seeking more power, this option builds boost at lower RPMs, providing additional power where needed. It delivers an extra 1.5psi of boost at redline, ensuring added horsepower to conquer challenging situations.

Enhance the performance of your Mini with the ALTA Lightened Crank Pulley (LCP), engineered to increase horsepower and torque. Available in 0% Stock Sized and +2% Oversized options, this pulley is crafted from 6061T6 aluminum, weighing only 0.65 lbs. Significantly lighter than the stock crank pulley, the ALTA LCP ensures improved engine efficiency without adding vibration or noise. The +2% Oversized pulley provides additional boost for Supercharged Cooper S models, delivering safe and reliable performance. With increased belt contact, this pulley reduces wear and enhances durability, making it a must-have upgrade for Mini enthusiasts.
